vmware 配置不同网段双网卡。

 一、前言

需求:由于LVS演练需要,需要配置两张linux OS网卡,而且是不同网段。

准备:

物理机:单网卡

VMware:centos 6.8

二、配置

 

第一步:新建虚拟机VMware,centos 6.8,默认有一张网卡eth0。配置的NAT模式,如图:

 

 

我这里NAT模式设置的网段是192.168.229.0/24网段。

 

 

第二步:添加一块网卡。模式为桥接,和物理机网段一样是192.168.1.0/24 网段。如图。

 

 

 

到这里,添加完了。

 

第三步、配置

Centos开机后,只有一张网卡eth0的信息,拷贝一张eth0的配置文件:

[root@ShiYanLou network-scripts]#cd /etc/sysconfig/network-scripts

[root@ShiYanLou network-scripts]#cp ifcfg-eth0 ifcfg-eth1

修改配置文件ifcfg-eth1:

[root@ShiYanLou network-scripts]# cat /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.

# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:df:72:dd", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:df:72:e7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

可以看到,eth1的mac地址是:00:0c:29:df:72:e7,修改/etc/sysconfig/network-scripts/ifcfg-eth1 成如下:

[root@ShiYanLou network-scripts]# cat ifcfg-eth1 
DEVICE=eth1
HWADDR=00:0C:29:DF:72:E7
TYPE=Ethernet
UUID=a5370cfe-c84a-4b11-97ee-a96f34db9bba
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=static
IPADDR=192.168.1.111
NETMASK=255.255.255.0
GATEWAY=192.168.1.1

重启网卡:service Network restart。

[root@ShiYanLou network-scripts]# service network restart
正在关闭接口 eth0: [确定]
正在关闭接口 eth1: [确定]
关闭环回接口: [确定]
弹出环回接口: [确定]

[root@ShiYanLou network-scripts]# ip a

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:0c:29:df:72:dd brd ff:ff:ff:ff:ff:ff
    inet 192.168.229.133/24 brd 192.168.229.255 scope global eth0
    inet6 fe80::20c:29ff:fedf:72dd/64 scope link 
       valid_lft forever preferred_lft forever
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:0c:29:df:72:e7 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.111/24 brd 192.168.1.255 scope global eth1
    inet6 fe80::20c:29ff:fedf:72e7/64 scope link 
       valid_lft forever preferred_lft forever

可以看到,两块网卡配置成功。
